Places he recommended for observing the phenomenon included Hudson Bay, Norway and the Molucca Islands. [6] The next transits would occur in 1761 and 1769. Halley died in 1742, almost twenty years before the transit. [7]
Aware of this, the English astronomer Edmond Halley made observations of such a transit on 28 October O.S. 1677 from the island of Saint Helena, but was disappointed to find that only Richard Towneley in the Lancashire town of Burnley, Lancashire had made another accurate observation of the event, whilst Gallet, at Avignon, had simply recorded ...
By convention, comets are named after their discoverer or discoverers, but several of the most famous periodic comets, such as Halley's Comet, discovered by Edmond Halley, and Encke's Comet, found by Johann Franz Encke, are in fact named after the person who first computed their orbit.

Edmond Halley, due to the lack of an assistant and only one vertical wire in his transit, confined himself to the use of a mural quadrant built by George Graham after its erection in 1725 at the Royal Observatory, Greenwich.
